Gold is a 6,000 year bubble.
BTC is a new bubble as well. Maybe BTC can be a new bubble and people make serious profits in a couple of years.maybe not..
USD = bitusd is a currency that will continue to lose it's purchase power since the US will continue to issue debt indefinitely.
So all in all the only way to retain your purchasing power is to have diversification to everything. You will lose from one but you will gain from the other. The important thing is that no matter what your investment appetite is, now you have a new choice. Trade and keep your assets in a decentralised bank and not be obliged to fully trust central banks and financial institutions.
